Using a consumer digital wallet as a payment method in a merchant digital wallet

ABSTRACT

A system is configured to perform operations that include receiving a purchase request to use a consumer digital wallet account of a user to pay for an item sold by a merchant, the consumer digital wallet account being included as a payment method in a merchant digital wallet account provided by the merchant to the user. The operations further include generating a single-use payment token based on a non-transactable token. Additionally, the operations include transmitting, to an existing card payment network, a card transaction message that includes the single-use payment token, the single-use payment token causing the existing card payment network to route the card transaction message back to the system. The operations also include causing payment to be remitted from the user to the merchant using a payment method included in the consumer digital wallet account.

BACKGROUND

Digital wallets that store different payment methods for a user have recently become more popular. As such, various types of digital wallet options may be available for a user. For instance, the consumer may have a consumer digital wallet account with a payment provider that can be accessed or used with various merchants. As another example, the consumer may have a merchant digital wallet account that is maintained with a specific merchant. The consumer accesses or uses the merchant digital wallet account whenever the consumer shops with or purchases an item from the specific merchant. In certain situations, the consumer may desire the ability to access or use a consumer digital wallet account as a payment method within the merchant digital wallet account.

DETAILED DESCRIPTION

Systems and methods are provided for using a consumer digital wallet account as a payment method within a merchant digital wallet account. According to certain embodiments, the consumer digital wallet account may be provided to a user by a payment provider. For example, the user may have previously registered the consumer digital wallet account with a payment provide server associated with the payment provider. The payment provider server may be configured to process payment transactions related to using the consumer digital wallet account as a payment method. In other embodiments, the consumer digital wallet account may be provided to the user by a consumer wallet provider that is different from the payment provider. In such embodiments, a consumer wallet provider server may communicate with the payment provider server to facilitate certain payment transactions that use the consumer digital wallet account as a payment method. For example, as described in more detail below with respect to FIGS. 1-5, the payment provider server maybe configured to route certain payment transactions to the consumer wallet provider server, which may be configured to process those payment transactions.

The consumer digital wallet account may store one or more payment methods for the user that the user can access at different merchant sites at which the consumer digital wallet account is accepted. As used herein, payment methods may include, but are not limited to, credit cards, debit cards, gift cards, internal balances with the payment provider, balances with other payment providers, coupons, electronic checks, cryptocurrencies, and incentives. The user may be able to access the consumer digital wallet account using a website hosted by the payment provider and/or using a consumer digital wallet application (provided by the payment provider) executing on a user device of the user.

In some implementations, the consumer digital wallet account may be associated with a social media feed that the user can access, post to, and view. The social media feed may display information (e.g., icons, emoji, text, etc.) related to payment transactions that user has participated with other users that have consumer digital wallet account with the payment provider. For example, if a user participates in a particular payment transaction with a second user, a corresponding post detailing aspects of the particular payment transaction may be automatically posted on the social media feed of the user and/or the second user. Additionally, the social media feed of the user may also include posts of payment transactions between other users (e.g., transactions in which the user did not participate), such as between other users that are included in a contact list of the user, or between other users located within a vicinity of the user.

Furthermore, the user may be provided a merchant digital wallet account by a merchant. The merchant digital wallet account may be accessible by the user when the user shops with the merchant, such as when the user visits a website of the merchant or using a merchant digital wallet application provided by the merchant. To this end, the user may store one or more methods of payment within the merchant digital wallet account for purchase transactions the user makes with the merchant. Furthermore, different users may have their own respective merchant digital wallet accounts with the merchant, and each of the merchant digital wallet accounts may store different payment methods of their respective users.

According to certain embodiments, the user may desire to add the consumer digital wallet account as a payment method to store within the merchant digital wallet account. For example, the user may initiate a request, via the user device, to add the consumer digital wallet account as a payment method to the merchant digital wallet account. In some implementations, the user may initiate the request via the consumer digital wallet application while in other implementations, the user may initiate the request via the merchant digital wallet application.

The request may include a account identifier associated with the consumer digital wallet account. In addition, the user device may transmit device information associated with the user device to the merchant server. The device information may include model information, an operating system version, language information, a device identifier, location information, and/or the like. Further, the device information may be included in the request or may be transmitted separately from the request.

The merchant server may receive the request and the device information and forward the account identifier and the device information to a payment provider system of the payment provider (which maintains the consumer digital wallet account for the user). Based on the account identifier and the device information of the user device, the payment provider system may perform a risk assessment of the request to add the consumer digital wallet account to the merchant digital wallet account. In response to determining, based on the risk assessment, that the request is approved, the payment provider system generates an electronic non-transactable token (NTT) corresponding to the consumer digital wallet account. In some implementations, the NTT may be a random string of alphanumeric characters that represents the consumer digital wallet account. Further, the NTT is unusable for payment (e.g., the NTT is unusable and/or unrecognizable by a payment network used to process payment transactions) and does not include any financial information related to the user nor data related to any financial instrument of the user. In addition, the presence of the NTT may indicate that consumer digital wallet account is valid payment option of the user within the merchant digital wallet account.

The NTT may be stored, in association with the account identifier, in a secure database separate from the merchant server. Moreover, the secure database is inaccessible by the merchant servers, and merchant, merchant severs, and/or any other device of the merchant do not have access rights to the secure database. However, the secure database is still accessible by the payment provider system. In addition, the NTT may also be transmitted to the merchant servers and stored on the merchant servers.

Subsequent to the generation and storage of the NTT, the user may initiate a purchase request to purchase an item from the merchant. The purchase request may indicate a selection of the consumer digital wallet account from the merchant digital wallet account as a payment method to complete the transaction. The purchase request may be received by the merchant server, and the merchant server may forward the purchase request to the payment provider system. The purchase request may include the account identifier of the user that is associated with the consumer digital wallet account. As such, the payment provider system may use the account identifier to retrieve the NTT from the secure database. As previously discussed, the existence of the NTT may indicate that the consumer digital wallet account is a valid payment method within the merchant digital wallet account.

Since the NTT is unusable for payment, the payment provider system may generate a single-use payment token based on the NTT. The single-use payment token may be another electronic token that is different from the NTT. Additionally, an association between the single-use payment token and the NTT may be stored in the secure database. Thus, the secure database may store associations between the NTT, the account identifier, and the single-use payment token. Further, the single-use payment token may include another set of random alphanumeric characters. Similar to the NTT, the single-use payment token does not include any financial information related to the user nor data related to any financial instrument of the user. However, in contrast to the NTT, the single-use payment token is usable for a single payment transaction (e.g., the purchase request). Therefore, after the purchase request is processed using the single-use payment token, the single-use payment token is no longer usable for subsequent purchase transactions.

The payment provider system may transmit a card transaction message that includes the single-use payment token to an existing payment network. In certain implementations, the existing payment network may be a credit/debit card payment network, and the single-use payment token may include a bank identification number (BIN) that corresponds to the payment provider and/or payment provider system. The card transaction message may be a card authorization message (e.g., an International Organization for Standardization (ISO) 8583 car authorization message) that represents a message format for authorization of credit/debit cards over the exiting payment network.

Based on the BIN include in the single-use payment token, the card transaction message may be routed back to payment provider system after being transmitted to the existing card payment network. Thus, payment provider system may in effect emulate the consumer digital wallet account as a typical credit/debit card and leverage an existing mechanism in place that is already used to process credit/debit card transactions (e.g., routing the card transaction message through the existing payment network). Further, in a typical credit/debit card transaction, the existing payment network routes the card transaction message to an issuer that is a different financial institution than the financial institution associated with the merchant. Present embodiments, as previously discussed, enable the card transaction message to be routed back to the payment provider system, with the payment provider providing the role of an issuer.

After the card transaction message is routed back to the payment provider system, the payment provider system may determine the account identifier using the single-use payment token. For example, based on accessing the secure database, the payment provider system may identify the NTT that is associated with the single-use payment token. Further, the payment provider system may determine that the NTT is associated with the account identifier.

Based on the account identifier, the payment provider system may retrieve wallet information corresponding to the consumer digital wallet account, such as a default payment method, wallet balance, payment history, and/or the like. Using the wallet information and/or other information (e.g., merchant information, transaction information such as purchase amount, date, etc.), the payment provider system may execute a risk analysis process with respect to the purchase request. In response to determining, based on the risk analysis process, that the purchase request is authorized, the payment provider system may cause payment from the user to the merchant using the consumer digital wallet account.

Further, according to certain embodiments, the user device may be configured to generate a post corresponding to the purchase transaction with the merchant on the social media feed of the consumer digital wallet account. For example, the user device may automatically generate particular text, icons, emoji, and/or the like in response to the purchase transaction being processed. Further, the particular text, icons, emoji, and/or the like that are posted my depend on the specific merchant corresponding to the purchase transaction. In other implementations, the particular text, icons, emoji, and/or the like maybe manually input by the user.

For example, the other applications 134 may include a GUI configured to provide an interface to the user.

The risk server 130 may further include a database 136, which may be stored in a memory and/or other storage device of the risk server 130. The database 136 may include, for example, IDs such as operating system registry entries, cookies associated with the risk analysis application 132, biometric information, IDs associated with hardware of the network interface component 138, IDs used for payment/user/device authentication or identification, and/or other appropriate IDs. According to a particular embodiment, the database 136 may also store a merchant identifier associated with the merchant, a location identifier associated with the merchant location, and/or a POS identifier associated with the user device 102.

In various embodiments, the risk server 130 also includes at least one network interface component 138 that is configured to communicate with the payment provider server 114 via the network 150. For example, according to a particular embodiment, the risk server 130 may receive voice communication information from the user device 102 via the network interface component 138. The network interface component 138 may comprise a DSL modem, a payment provider server 114TN modem, an Ethernet device, a broadband device, a satellite device and/or various other types of wired and/or wireless network communication devices including microwave, RF, and IR communication devices.

The network 150 may be implemented as a single network or a combination of multiple networks. For example, in various embodiments, the network 150 may include the Internet or one or more intranets, landline networks, wireless networks, and/or other appropriate types of networks. Thus, the network 150 may correspond to small scale communication networks, such as a private or local area network, or a larger scale network, such as a wide area network or the Internet, accessible by the various components of system 100.

The payment network 160 may be implemented as a single payment network or a combination of multiple payment networks. For example, in various embodiments, the network 160 may include one or more payment rails operated and maintained by one or more financial institutions such as VISA®, MASTERCARD®, STAR®, PULSE®, and/or the like. The payment network 160 may also include secure connections between the user device 102 the payment processor 114 and one or more payment gateways.

FIG. 2 illustrates a data flow 200 for adding a consumer digital wallet account of a user to a merchant digital wallet account of a merchant. FIG. 3 illustrates a flow diagram of a method 300 for adding a consumer digital wallet account of a user to a merchant digital wallet account of a merchant. As such, FIG. 3 will be described in conjunction with references to elements illustrated in FIG. 2. Note that one or more steps, processes, and methods described herein may be omitted, performed in a different sequence, or combined as desired or appropriate. As previously discussed, the consumer digital wallet account may be provided to the user by the payment provider, and the merchant digital wallet account may be provided to the user by the merchant for use when the user purchases an item or other product from the merchant.

At step 302, the payment provider server 114 may receive a request to add a consumer digital wallet account to the merchant digital wallet account. For example, as shown in FIG. 2, the user device 102 may transmit a request 202 to add the consumer digital wallet account as payment method within the merchant digital wallet account for use in subsequent purchase transactions with the merchant. For example, the user device 102 may transmit the request 202 using the digital wallet application 104 provided by the merchant and stored on the user device 102. As another example, the user device 102 may transmit the request 102 via a website provided by the merchant server 140. As such, the request 202 may be transmitted in response to the user selecting (e.g., via the user device 102) the consumer digital wallet account from a plurality of payment methods offered to the user via the digital wallet application 104 and/or the website. In other embodiments, the request 202 may be transmitted by the user device via the consumer digital wallet application 105. For instance, the user may add the consumer digital wallet account as a payment method to the merchant digital wallet account from within the environment of the digital wallet application 104.

The merchant server 140 may receive the request 202, such as via the merchant wallet application 142. The merchant wallet application 142 may be configured to forward 204 the request to the payment provider system 230. According to some embodiments, the payment provider system 230 may include components from the payment provider server 114 and the risk server 130. For instance, the payment provider system 230 may include the digital token application 116 and the wallet account application 120 of the payment provider server 114 and the risk analysis application 132 of the risk server 130.

At step 304, the payment provider server 114 may determine device information of the user device 102 and a account identifier associated with the consumer digital wallet account. For instance, the wallet account application 120 may receive the forwarded request 204 from the merchant server 140, and the forwarded request 204 may include login credentials provided by the user. Based on the login credentials, the wallet account application 120 may authenticate user and determine a account identifier corresponding to the login credentials. The account identifier may be linked to and/or otherwise associated with the consumer digital wallet account provided to the user by the payment provider. In other embodiments, the forwarded request 204 itself may include the account identifier. Further, the forwarded request 204 may also include the device information associated with the user device 102. As such, the wallet account application 120 may transmit a risk analysis request 206 that includes the account identifier and the device information. As previously discussed, the device information may include model information, an operating system version, language information, a device identifier, location information, and/or the like.

At step 306, the payment provider server 114 may determine, based on the device information and the account identifier, whether the addition of the consumer digital wallet account to the merchant digital wallet account is authorized. For example, the risk analysis application 132 may receive the risk analysis request 206. Based on the account identifier and the device information included in the risk analysis request 206, the risk analysis application 132 may determine whether the addition of the consumer digital wallet account to the merchant digital wallet account is authorized. At step 308, if the risk analysis application 132 determines that the addition of the consumer digital wallet account to the merchant digital wallet account is authorized, the risk analysis application 132 may transmit an authorization indication 208 to the wallet account application 120. Further, the method may then proceed to step 310.

At step 310, the payment provider server 114 may generate a NTT corresponding to the consumer digital wallet account. For instance, in response to receiving the authorization indication 208, the wallet account application 120 may transmit a token request 210 to the digital token application 116. The digital token application 116, in response to the request, may be configured to generate the NTT. As previously noted, the NTT may represent an indication that the consumer digital wallet account has been added as a valid payment method to the merchant digital wallet account. In certain implementations, the NTT may be a randomly generated string of alphanumeric characters, although it will be appreciated by one or ordinary skill in the art that other representations of the NTT are also possible. As previously discussed, the NTT is unusable for payment and does correspond to any particular financial instrument of the user.

At step 312, the payment provider server 114 may store the NTT in a secure database. For example, the digital token application 116, in some instances, may be configured to store an association between the NTT and the account identifier in secure database 240. According to some embodiments, the secure database 240 may correspond to the database 124 of the payment provider server 114 or any other database accessible by the payment provider server 114. In addition, the secure database 240 may be inaccessible to the merchant server 140. In other words, the merchant server 140 may not have access rights to the secure database 240 and/or may be unauthorized to access the merchant server 140.

At step 314, the NTT may be transmitted to the merchant server 140. For instance, the payment provider system 230 may transmit 214 (e.g., via the payment provider server 114 or a consumer wallet provider server) the NTT to the user device 214. Further, the user device 102 may provide 216 the NTT to the merchant server 140 to be stored locally at the merchant server 140 or in a storage device associated with the merchant server 140.

FIG. 4 illustrates a data flow 400 for selecting the consumer digital wallet account as a payment method from the merchant digital wallet account for a purchase transaction. Similarly, FIG. 5 illustrates a flow diagram 500 for selecting the consumer digital wallet account as a payment method from the merchant digital wallet account for a purchase transaction. Thus, FIG. 5 will be described in conjunction with references to elements illustrated in FIG. 4. It will be appreciated that the steps discussed with respect to FIG. 4 and FIG. 5 may be performed subsequent to adding the consumer digital wallet account to the merchant digital wallet account as previously described with reference to FIG. 2 and FIG. 3. Note that one or more steps, processes, and methods described herein may be omitted, performed in a different sequence, or combined as desired or appropriate.

At step 502, the payment provider server 114 may receive a purchase request to use the consumer digital wallet account as a payment method to pay for a product or item sold by the merchant. For instance, the user device 102 may transmit a purchase request 402 to the merchant server 140, and the merchant server 140 may forward 404 the purchase request to the payment provider system 230. In certain embodiments, the purchase request 402 may include device information associated with the user device 102 as well as the account identifier that was provided to the user by the payment provider. Further, the merchant server 140 may add additional information to the forwarded request 404, such as transaction information associated with the purchase request (e.g., information related to the item to be purchased from the merchant, a payment amount, and/or other types of transaction information) and merchant information associated with the merchant (e.g., a merchant identifier, merchant location information, and/or other types of merchant information).

At step 504, the payment provider server 114 may retrieve an NTT corresponding to the account identifier from a database. For example, the digital token application 116 may use the account identifier to retrieve 406 the NTT from the secure database 240. As previously discussed, the secure database 204 may store an association between the account identifier and the NTT and may be inaccessible to the merchant or merchant server 140. In certain embodiments, the account identifier may be used as an index into a table that stores multiple associations between different NTTs and different account identifiers.

At step 506, the payment provider server 114 may determine whether the NTT is in fact stored in the secure database 240, and if so, the method 500 may proceed to step 508. Otherwise, an error may be returned to the payment provider server 114 and forwarded to the merchant server 140 and/or user device 102.

At step 508, the payment provider server 114 may generate a single-use payment token based on the NTT. For instance, the digital token application 116 may generate a single-use payment token based on the NTT. According to one or more embodiments, the single-use payment token may include a bank identification number (BIN) corresponding to the payment provider and/or payment provider server 114. Additionally, an association between the single-use payment token and the NTT may be stored in the secure database 240. As a result, the secure database 240 may store associations between the single-use payment token, the NTT, and the account identifier. Further, it will be appreciated that the single-use payment token may be a digital cryptographic token that can be used for a single payment transaction (e.g., the payment transaction corresponding to the purchase request of the user to purchase the item from the merchant). After processing the payment transaction, the single-use payment transaction may remain unsuable for subsequent payment transactions.

At step 510, the payment provider server 114 may transmit, to a payment network, a transaction message that includes the single-use payment token. For example, the digital token application 116 may provide 408 the single-use payment token to the payment processing application 118, and the payment processing application 118 may generate the transaction message that includes the single-use payment token. The payment processing application 118 may then transmit 410 the transaction message to the payment network 160. In some embodiments, the transaction message may correspond to a credit/debit card transaction message (e.g., an ISO 8583 authorization message). Further, the payment network 160 may be an existing card payment network that routes credit/debit card transaction messages to the appropriate devices.

In embodiments where transaction message corresponds to a credit/debit card transaction message, the digital token application 116 may generate the transaction message to include dummy card account information. For example, the transaction message may include a dummy expiration date, a dummy card verification value (CVV) number, other types of credit card information, and/or a combination thereof. Thus, the transaction message may mimic a credit/debit card transaction message, and the payment network 160 may be able to process the transaction message as a normal credit/debit card transaction.

According to other embodiments, prior to or concurrently with transmitting the transaction message to the payment network 160, the payment processing application 118 may cache 411 certain transaction information and merchant information with the risk analysis application 132 to be used during execution of a subsequent risk analysis process (e.g., as discussed with respect to step 516 below). The transaction information may include, but is not limited to, information related to the user/buyer, account details of the user/buyer, transaction amount, currency, transaction type (e.g., whether the transaction is an authorization transaction or a sale transaction), and a payment type. The merchant information may include, but is not limited to, information corresponding to merchant identifiers, merchant accounts, and merchant location. As an example, the payment processing application 118 may associate a unique identifier with the transaction information and the merchant information. To this end, the payment processing application 118 may generate the unique identifier by using a hash function to calculate a hash value based on the single-use payment token and the dummy card account information. Further the payment processing application 118 may store and/or cache the association between the unique identifier (e.g. the hash value) and the transaction and merchant information with the risk server 130, such as in the databased 136 or another storage component in communication with the risk analysis application 132.

At step 512, the payment provider server 114 may receive the transaction message that has been routed back to the payment provider server 114 based on information included in the single-use payment token. For instance, based on the BIN included in the single-use payment token, the transaction message may be routed 412 from the payment network 160 back to the payment provider server 114 (e.g., the payment processing application 118). For example, the payment network 160 may perform a lookup to a routing table using the BIN and determine that the transaction message is to be routed to the payment provider server 114 based on the lookup.

At step 514, the payment provider server 114 may determine, based on information included in the single-use payment token, wallet account information associated with the consumer digital wallet account. For instance, the payment processing application 118 may identify, based on de-tokenizing the single-use payment token, certain information that includes, but is not limited to, a second unique identifier, the account identifier corresponding to the consumer digital wallet account, and user information related to the user. According to some embodiments, the second unique identifier may be a second hash value calculated by the payment processing application 118 using the same hash function used to calculate the hash value that was previously cached and associated with the transaction information and merchant information. As such, after the transaction message is routed back to the payment provider server 114, the payment processing application 118 may calculate the second hash value by applying the hash function to the single-use payment token and the dummy card account information that was included in the transaction message. Additionally, the payment processing application 118 may determine the account identifier based on the association between the single-use payment token, the NTT, and the account identifier stored in the secure database 240.

Further, the payment processing application 118 may provide 414 the information resulting from the detokenization of the single-use payment token (e.g., the second unique identifier, the account identifier, and/or the user information) to the wallet account application 120. The wallet account application 120 may determine whether access to the consumer digital wallet account is authorized, and if so, the wallet account application 120 may determine, based on the account identifier, wallet account information corresponding to the consumer digital wallet account. The wallet account information may indicate a default payment method for the user that has been selected from a plurality of payment methods of the user stored in the consumer digital wallet account. The wallet account information may also include other information related to the consumer digital wallet account, such as transaction history of the user's usage of the consumer digital wallet account and other types of information. Furthermore, the wallet account information, the second unique identifier, the user information, or a combination thereof may be provided 414 to the wallet account application 120.

As previously discussed, the wallet account application 120 may be executed by a different server than the payment provider server 114. For example, the wallet account application 120 may be executed by the consumer wallet provider server dedicated to managing the consumer digital wallet account of various users of the payment provider. To this end, the payment processing application 118 may transmit the information resulting from the detokenization of the single-use payment token to the consumer wallet provider server. The consumer wallet provider server may then determine the wallet account information from the detokenized information and provide the wallet account information to the risk server 130, as detailed in step 516.

At step 516, a risk analysis process with respect to the purchase request may be executed using the wallet account information. In certain embodiments, in addition to using the wallet account information, the risk analysis process may also be executed using the cached transaction information and merchant information and the user information. For example, the risk analysis application 132 of the risk server 130 may determine that the second unique identifier is equal to the unique identifier that was previously cached with the transaction information and the merchant information in the database 136. For instance, the second unique identifier may be the second hash value, and the risk analysis application 132 may determine that the second hash value is equal to the previously calculated and cached hash value. Based on this determination, the risk analysis application 132 may access the transaction information and the merchant information associated with the previously calculated and cached hash value.

At step 518, the payment provider server 114 may determine, based on the risk analysis process, whether to proceed with the processing the purchase transaction. For example, based on executing the risk analysis process, the risk analysis application 132 may determine a risk profile associated with the purchase transaction. Further, the risk analysis application 132 may determine whether the risk profile satisfies a risk threshold. If the risk profile satisfies the risk threshold, the method 500 may proceed to step 520, in which the purchase request is processed. Otherwise an error may returned and transmitted to the merchant server 140 and/or user device 102 indicating that the purchase transaction could not be processed.

At step 520, the purchase request is processed, thereby causing funds to remitted from a financial account of the user to a financial account of the merchant.
